Flashback to a scene where the assistant agrees to accompany the professer, and an indian guide on an exploration of the Grand Canyon, and some unexplored caverns there.

The professor tells about a little known custom of the plains indians locking people in caves as a trial of manhood. A strange rock formation seems to offer the chance to investigate that legend. It means blasting away a landslide, and checking it out. The findings prove something else though.

A wagon train has been found that is estimated to be at least a hundred years old. Maybe there’s nothing to the legend, or maybe something else that is unexpected begins to develop. Here’s some hints. Get ready for savage killings, horrors in the bowels of the earth, and a narrow escape.

But remember that opening scene? the girlfriend who found her lover cowering? What kind of harrowing experience has brought him to that state? And what about that locked door? Join the expedition into a world where it’s survivla of the fittest, and evolution runs at has to be time lapsed speed.
